JAMES H. BARRETT, OF EL DORADO, ILLINOIS, ASSIGNOR TO HIMSELF AND JAMES SHAVER, OF SAME PLACE.'

HORSE-DETACH ER.

SPECIFICATION forming part of Letters Patent No. 265,000, dated September 26, 1882.

Application filed July 18, 1882. (No model.)

To all whom it may concern:

Be itknown that l, J AMEs H. BARRETT, of El Dorado, Saline county, Illinois, have invented a new and Improved Horse-Detacher, of which the following is a full, clear, and exact description.

trivance whereby the evener may be tripped bythe driver and caused by the horses to turn, ro so that the traces Will'detach and allow the carriage to be disconnected from the horses when theybecome uncontrollable, the arrangement by which the same is accomplished being very simple, cheap, and effective, and applicable to two or three horse eveners, also to mowing and harvesting machines, as well as to Wag; ons and carriages, all as hereinafter fully described.

Reference is to be had tothe accompanying 2o drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the gures.

Figure l is a perspective view, and Fig. 2

is a side elevation, of my improved detaching z5 apparatus, the evener being in the detaching position in the latter gure.

I pivot the 4evener a to a flat bar of iron, b, that is hinged Aat c, in front of the evener, to another short bar, d, that is securely attached to the tongue q in front ofthe hingey joint. The bar b extends along the top ot' the tongue, back of the evener, asuitable distance, and at the rear end it is conined to the tongue by a yoke, c, that is so pivoted to the tongue atfthat it may swing back off from over the end of said bar, so as to free the latter and allow the draft of the traces on the evener to swing the latter upon hinge c along the quadrant-bar g, so'that the hooks h of the whiffle- 4o trees t' will unhook from the traces, thus disconnecting the carriage or machine at any time it may be required to do so for safety.

lnsteadof the yoke efor holding and disconnecting the bar b, Va sliding latch-bolt may i be employed, and it may be made to trip and My invention consists of an improved con-V release the evener-bar by means ot' a cord or wire extending back to the drivers place; but for harvesters and other machines I prefer to employ the lever j and latch arrangement lf l, the lever j being connected to the arm of the 5o yoke by the rod, which may be long or short, according to the distance back of the evener that it may be desired to set the lever j.

I prefer to employ auxiliary evener m and connecting-rods a', together Wit-h the above-de- 55 scribed detaching apparatus, for the better control of the evener a, by lessening the torsional strain of the evener al on the pivot-bolt o. It also prevents the evener a from vibrating vertically and transversely of the tongue 6o to some extent.

The sector-bar g is a guide to control the evener laterally when swinging up along it. Said bar is supported by the upright p at the front of the evener, and Aback of it said bar passes through a slot of the bar b and is firmly attached to the tongue.

I am aware that it is not new to use a retractile slide in a slotted tastin g on the thill cross-bar in combination -with a single-tree piv- 7o oted to said casting 'havinfr a catch to en aoe b b D the slide and provided with slotted tug-clips at its ends; also, that it is not new to use a pull-back lever in connection with the brake while a-spring presses a pawl into the notches 7 5 of a ratchet; also, that it is old in equalizers to employ sin gie-tree levers pivoted to the double-tree and connected by pivoted rods to a middle pivoted cross-bar; but

What I claim as new and of my invention 8o The combination of the evener a., the bar b,

hinged in front thereof to a short bar, d, on

the tongue, the yoke e, pivoted to the tongue at f, and the whiffletrees having hooks h, all

arranged substantiallyas shown and described.
